A= 3000(1+.036/12)^72
Algebra 2 compound interest

Answers

First we need to simplify (.036)/(12) to 0.003.

We get 3000(1+0.003)^(72)

Now we simplify 1+0.0031+0.003 to 1.0031.003.

3000×1.003^(72)

Simplify {1.003}^{72}1.003 to 1.2407011.240701.

3000×1.240701

Then we simplify to 3722.103387.

Write 7 over 10 as a percentage

Answers

70%

A percentage is the same thing as a fraction with a denominator of 100. To make our current denominator change to 100, we must multiply it by 10. So, we must do the same thing to the numerator. 7 times 10 is 70, and 10 times 10 is 100. This means 7/10 equals 70/100, which is 70%.
